'Application filed March 24, 1914. Serial No. 826,952.

To all whom itmay concern.'

Be it knovvnthat rife, CHARLES H. SHEP- LER, a citizen ot the United States, and

JOSEPH W. Sramana, a subject of the King of England, residing in the city and county of San Francisco and State of California,

' lar boilers; the'eleaning 'being eifected by injecting a. jet of steam or lother fiuid under pressure through theseveral tubes from the rear, discharging the rein'ove'd material te the smoke box front.

The present invention' is particularly designed for: the cleansingoii .smokel tubes or i'iues of boilers, or the like, the apparatus being connectible to the lront of the boiler andincluding a rotary and longitudinally movable spray or nozxleY member connected by a suitable conductor to a feed head at* tachable to the front end of the boiler.

A special feature of the present invention is the provision oi a. means for longitudinally and rotatably moving the spray nozzle, said means comprising a rotary crank which is so'mounted and connected to the headl of the apparatus, at the front of the boiler, that it will not longitudinally shift and will thus be particularly useful in stolre holes ot eonning proportions Where it would be impractical, if not impossible, to utilize an apparatus attached to the front of the boiler ii such apparatus required room for a longitudinal movement toward and from the 'front of the boiler.

To accomplish these ends, the apparatus consists of a head or 'main body portion suit' ably attachable to the front sheet or panel of tthe boiler adjacent to the smoke boa.

whereupon .its threaded part cooperating with the fixed threaded body will be shifted longitudinally without any longitudinal movement of the crank-shaft.

The invention consists of the parts and the construction 'and combination of parts as hereinafter' more fully described and claimed, having reference to the accompanying drawingain Which Figure l is a vertical sectional View through a boiler, showing the apparatus as installed for use. Fig. 2 is a central longitudinal sectioned view through the apparatus.

ln the present embodiment of our invention, the apparatus includes a tubular body member or barrel l, which may be applied and fixed to sonic lpart of the boiler front and secured thereto in Aa suitable manner when it is desired to clean the tubes. The bore' of this barrel l is threaded inside to receive a. cylindrical nut 2, which latter has its threads outside so that it can be screwed into the threaded bore of the barrel l and is capable ci being turned in the barrel and during its turning movement moves longitudinally according to the direction of r0- tation. 'l`hrough this barrel and in the nut is passed a crank-shafted which is turnably mounted in the outer or head end of the barrel l between suitable saoulders; the outer end ot the crank-shaft being provided with a crank 17 vwhereby it may be rotated. The crank-shaft 3 is in the present case mounted Within a conductor l, upon the` inner end of `which is formed or secured the nut 2. The conductor is provided adjacent to the nut end with ports 5 through which steam entering an inlet or supply connection l5 may find access te the interior oit the conductor 4. The nut 2 is provided with longitudinally extending exterior grooves or channels 6, `allowing the ilow of the steam from the inletor head'end into the barrel l and thence" through the ports 5 into 'the conductor 4. The conductor extends beyond therear end ot' the barrel 1, which is provided with a suitable packing gland 9, through which the Conductor 4 slideswhen the crank-shat is turned and the nut 2 engaging the internal threads oi:l the barrel l produces a longitudinal movement of the conductor 4.

There may be connected to the inner end et the conductor et, by any suitable coupling device indicated by 'a union. 23, an extension pipe or conductor e. having at' its opposite mesnil ported Iagainst longitudinal movement in said body member and operatingy to revolve said conductor and canse its longitudinal movement within the internally threaded tubular body member and-i ta nove its discharge toward and away from the'inner-end of the body member.

ln an apparatus lor cleaning boiler lues or the like, a tubular body member nonthreads in the'tubular body member where by, when the crank-shaft is rotated, said conductor 1s caused to shift longitudinally mdependentlywof and rotatively with the eranlnshaft.

'tfrlhe combination in an apparatus for cleaning boiler lines, of a body member at tacbable to ay convenient portion ot' the boiler7 means 'for supplying a. fluid under pressure to said body member, a conductor sl'idably and rotatively connected to and extending` from one end of said body member and carrying a spray nozzle for directing a spray ot fluid under pressure obliquely ton'a rd the adjacent ends ot the Aboiler fines, an operating;1 shaft held against longitudinal movement and having free rotary movement vin said body member and turnably engaging the inner and adjacent end ot said conduotor, and means for shitting the conductor and therewith the nozzle longitudinally in'- dependently of said operating shaft while the latter and the conductor are rotatively opera ting.

el. lvleans for sweeping a boiler flue or tube plate with a jet yof steam directed at an oblique' angle to 'said plate, comprising a conductor having a nozzle at one end for directingr the 4ict obliunely, said conductor being,r inscrtible and supported in. one of the dues. and non-slidabl means for revolvingr said conductor to move the jiet of steam in a circle and -tor longitudinally moving the nozzle 'from and toward said flue or tube plate to increase or decrease the diameter ot the circle.

llleans 'tor smashing; a boiler flue or tube plate with a jiet ot steam directed at an oblique anfle to said plate, comprising` a condurtor having a nozzle at one end vt'or directing;r the 4iet obiiouely. said conductor being` insertible and sui'uiorted in one of the l lines, and means' torY revolving said conductor to move the jet of steam in a circle and .for moving the nozzle from and towardlsaid line or' tube plate to increase or decrease the diameter of the circle, said last named means i including threads on. the inner end oitthe 70 conductor, Yal stationary partengaged by 'said threads, and a crank-shaft operative rotatively upon said threaded part and being held against longitudinal movement.
